I guess I'm still confused then, b/c I thought a QT should have a filter and heater, etc and that would be difficult in a bucket or container. Also if the fish are going to be in QT for a while (QT new fish should take at least a month from what I've heard and if they are sick and being treated with meds it can also take a while), and if meds are added to a container with out filtration then daily water changes would be needed since the container wouldn't be cycled, etc. Wouldn't that just be more stress on already stressed and sick fish? Not to mention a waste of meds.
If someone else could clarify that would be great.
